This is "Tiny Run for Your Lifes!" a 2-player game that needs the players to avoid getting squashed by walls (black) or forcefully fall into lava (red). You are given springboards (yellow) to overcome the lava and the occasional mechanism to slow down the world a bit (green).
Grab a friend and challenge them to this small minigame. As this is NOT a Co-Op game, feel free to be as sneaky and mischievous as you can be, but never forget: "Have Fun! And DONT DIE!"
